perhaps it's like putting a rubber ball into the frezer,let it be hard rock(brittle),then take it out,it'll be in it normal condition again.WhaJOM; I can discuss the behavior of ferrous materials used in the boiler and pressure vessel industry.The answer to your first question is no.FerrJOM,in order to give you a better understanding of this phenomenon,I'll refer you to my reply in thread330-110691 ,where a detailed explanationAdding a little to above posts by metengr and Salvito . Some metals that have very high (DBTT)are actually given a controlled cold treatment (cryFor a clearer understanding of the metallurgy of the Titanic,I suggest the following website http://w ww.metallu rgy.nist.g ov/webpage s/TFoecke/Thanks everyone.The answer seems to be that the steel recovers.J.one question that may be out of topic.Other than failure due to DBTT,didnt the relatively high sulphur content,hence the sulphur precipitates,hYes,there were several things that contributed to the failure and certainly high S in the rivets didn't help matters at all.

Smokstak Why Cold Steel Is BrittleAntique Engine Sep 20,2016 Why Cold Steel Is Brittle#0183;Re Cold Steel=Brittle Fracture? Mark,There is always a concern with the metallurgy.That is why the codes ask for documentation of the steel used.I have personal experience with steel from China,India and other places and there is always a concern.The concern with the titanic steel was phosphorous or sulfer inclusions causing brittle steel. Cold Steel Medium Warcraft Tanto,5 1/2 This knife,in this steel,at this price (160),is a steal! This knife is big,sturdy,and made of 3V super steel.Cold steel finally made an actual full tang knife and I love it! It can be used as a tactical knife or a camp tool.The handle feels great and it came hair shaving sharp.The sheath has amazon retention and an easy snap on belt loop. Cold Steel MAA Italian Long Sword,Black This is my 2nd Cold Steel piece.I also have the 1-hander Arming sword,and I'm reasonably happy with both.They are just wall hangers for me which is probably why I like them so much.Less ornate than typical wall hangers and at least double the cost,but I like knowing they are real steel and at least somewhat functional.
